Quiz: It is important to follow safety procedures when installing and
handling fiber optic cable. What should you use to pick up fiber
pieces after you splice a cable?
Ans: Tweezers
Quiz: You are doing an aerial installation of fiber optic cable. When
you survey the installation path, you see that the path runs near
several short outbuildings and over a series of hedges. Which
installation method should you use?
Ans: The pull in method
Quiz: Poor performance in the fiber optic network leads you to
believe that there is a fault in the fiber optic cable and you want to
test a section of the network with an optical time domain
reflectometer OTDR, How should you connect the OTDR to the
fiber optic cable?
